San Francisco- Apple Inc is hosting a music-themed event Wednesday that is likely to yield updated iPods and iOS 4.1, though the company will not confirm any details.The main focus of the event was iPods, ostensibly -- Apple claimed to have sold 275 million of them to date. And at the event, Apple chief Steve Jobs unveiled a slimmer new version of the Touch including "Retina display," the 24-bit high-quality screen that Apple introduced with the newest version of its iPhone.Jobs called the Touch "the number-one portable game player in the world," noting that over a billion games and entertainment titles have been sold for it. Though the new Touch shares other hardware similarities to the latest iPhone (such as front and back cameras), it doesn't have cellular connectivity, and therefore won't share the radio issues that haunt the new iPhone.iPod Touch: Still Top DogNo surprise here: the iPod touch retains its five-star rating and Editor's Choice award for its excellent fourth generation model, which finally includes two cameras, one for still shots and video, and the other for FaceTime video chat, which works seamlessly. And the addition of Game Center for social gaming, and Ping for social networking only promise to make your iPod experience more fun. Every year now, with the touch, Apple seems to outdo itself and leave the competition scrambling. In fact, at this point, the iPod touch doesn't really have much legitimate competition—it seems former competitors like Samsung are now focusing on tablets, like the upcoming Galaxy Tab, in an attempt to grab some of the iPad's considerable market share.iOS 4.1: Taking HDR photosOther thing we have more attention is the updated iOS 4.1. When iOS 4.1 ships this week, iPhone and iPod touch users will have a new feature that allows for better photos in bright lighting: High Dynamic Range. Apple Insider offers a first look at the new technology built right in to the iOS Camera application.HDR photos allow for superior pictures in daylight or other bright settings. Particularly when a shadow is cast on the subject or a part of the photo, it allows for a more accurate representation that doesn't allow the light or shadow sources to overpower the picture and result in a murky or discolored photo. The new feature aims to prevent photos that are "blown out" with too much light. It accomplishes this by taking three photos in rapid succession: one with normal exposure, one underexposed, and another overexposed.Tested on an iPhone 4, the HDR function is in fact a great option for users built right in to the native Camera application. If a picture is appropriately focused before it is snapped, the resulting photo is often superior to the regular picture.iOS 4.1 also fixes bugs that have existed in iOS 4, including a problematic proximity sensor issue that would cause the touchscreen to sometimes become active when a user was on a call. It also addresses problems with Bluetooth connectivity, and slow performance for users running the iPhone 3G.The latest version of iOS also brings the ability to upload HD video over Wi-Fi, including uploads to YouTube. It also allows for TV show rentals, which were unveiled alongside the new Apple TV introduced Wednesday. And iOS 4.1 also ships with Game Center, Apple's social media service for gamers with friend’s lists and achievements.iOS 4.1 has become available for recent generation iPhones and iPod touches on Wednesday Sept 8.To sum up, we find that the new version of iPod and iPhone adds the battery life, games, HDR photos, video and talking book etc functions, but the supported formats of video and audio don’t be added.Audio formats supported: AAC (8 to 320 Kbps), Protected AAC (from iTunes Store), HE-AAC, MP3 (8 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, 4, Audible Enhanced Audio, AAX, and AAX+), Apple Lossless, AIFF, and WAVTV and Video formats supported: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file formatThey could not support DVDs.
